Once the tool launches in Trace Mode, load your scatter file. You will notice a new panel: "Runtime Log" or "BROM Logging." Ensure "Save to file" is checked.
Before delving into Trace Mode, one must understand the base tool. A Smartphone Flash Tool communicates directly with a device’s boot ROM—code embedded in the processor that executes before any operating system loads. When a smartphone is powered off and connected via USB, the flash tool can bypass the main OS (Android, iOS, etc.) and read or write raw partitions like boot, recovery, system, or userdata. This capability is essential for unbricking devices, installing custom ROMs, or repairing corrupted software. However, standard flashing is a largely opaque process: the user sees a progress bar, but the intricate handshake between tool, CPU, and memory remains hidden.
